Programming drums using Patterns could be really sexy and a great feature for selling Studio One. But at best it's quite clunky.
Presonus should buy a touchscreen and use it as a secondary monitor to see what it's like for the Patterns editor when it's detached.
If nothing else, the Patterns editor needs an accent toggle - so people can continually add accented drum hits. In the real world, most electronic drum hits are main hits. The smaller inbetween hits are normally a lower velocity.
Adding a toggle for touchscreens (and generally) would really improve this aspect of Studio One when doing electronic music productions.
